IPC: H04N1/21
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a digital image output device that applies image output processing to an image with high productivity without causing an overflow regardless of a limited memory capacity. SOLUTION: When the size of a 1st page is detected (#23), a capacity reserved for a memory is decided by estimating a worst data compression rate (#24), the memory capacity is reserved so as not to be reserved by other image data and paper feeding is started (#33, #34 in a state 1). When it is not required to reserve an additional memory capacity for the 2nd and succeeding pages, paper feeding for the pages is immediately stated (#55 in a state 3). In the case that the additional capacity reservation is required, the additional memory capacity is reserved and paper feeding is started (#33, #34 in a state 4). Thus, the required memory capacity is dynamically reserved and printing is efficiently processed.

Title: Biaxial testing device for material
Inventor: ITO HISASHI
IPC: G01N3/02
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a testing device for biaxial material which has a simple structure and can perform loading tests on test pieces with accuracy in a state which is approximated to the actual using state of the material. SOLUTION: The loading direction to a test piece 12 is set in the plane containing the X-X axis and Y-Y axis and the loading direction by means of an actuator 16 is set in the Z-Z axis direction perpendicular to the X-Y plane. The Z-direction load from the actuator 16 is converted into a load in the X-Y plane through four arms 19a, 19b, 19c, and 19d. Since the load from the actuator 16 is not applied to the test piece 12 directly, but applied to the piece 12 after the load is converted into the load in the X-Y plane, a balanced load can be applied to the piece 12. Therefore, the tensile strength or compressive strength of the test piece 12 can be tested in a state which is approximated to the actual using state of the material.

Title: Polarizing element and optical head device
Inventor: ASADA JUNICHI
IPC: G11B7/1369
Filed: 1990-09-20
Abstract: PURPOSE:To simplify the constitution of the polarizing element which performs conversion between concentric polarized light and linear polarized light and to facilitate the formation of the element by composing the polarizing element of a TN liquid crystal layer which is oriented in one linear direction on one liquid crystal orienting surface and in the tangent direction of a concentric circle on the other surface. CONSTITUTION:The polarizing element 110A consists of one TN liquid crystal layer which is oriented in one linear direction on the side of a semiconductor laser 8 and in the tangent direction of the concentric circle on the side of a waveguide layer 100. Consequently, linear polarized light emitted by the semiconductor laser 8 is converged by a condenser lens 9 into parallel light a20, which is transmitted through the polarizing element 110A to become concentric light a21, but this concentric polarized light a21 is concentric polarized light a21 which has the same direction of an electric field vector at diagonal positions of the concentric circle since linear polarized light a20 incident on the polarizing element 110A is completely in phase. Consequently, the element constitution is simplified and the liquid crystal is oriented in the concentric circle tangent direction (rotating direction) on one side, and in the linear direction on the other side, so the element is easily formed.
